【発明の詳細な説明】
この発明は熱可塑性ナイロン樹脂をエポキシ樹脂層を介
して金属板上に密着させると共に表面にテフロン微粉末
層を一挙に形成できる樹脂組成物に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a resin composition capable of adhering a thermoplastic nylon resin to a metal plate via an epoxy resin layer and simultaneously forming a Teflon fine powder layer on the surface.
（従来技術）
ナイロンは表面滑性その他優れた性質を有しており、こ
の優れた性質を利用するため金属表面の被覆材として使
用されている。(Prior Art) Nylon has excellent properties such as surface smoothness, and to take advantage of these excellent properties, it is used as a coating material for metal surfaces.
しかしナイロン樹脂は金属に対する接着性が小さいため
にそ、の塗装に当たってはプライマー処理を必要とし、
このため塗装コストが高くなる欠点がある。However, since nylon resin has low adhesion to metal, it requires primer treatment when painting it.
For this reason, there is a drawback that the coating cost becomes high.
更にナイロン樹脂被膜は傷が付き易い欠点もある。Furthermore, the nylon resin coating also has the disadvantage of being easily scratched.
（本発明の目的）
本発明は静電塗装等においてプライマー処理が不要でし
かも塗膜表面に耐熱性滑択層又は滑性粗面を形成できる
粉末樹脂組成物を提供するものである。(Object of the present invention) The present invention provides a powdered resin composition that does not require primer treatment in electrostatic coating, etc., and can form a heat-resistant slipping layer or a smooth rough surface on the surface of the coating film.
（解決課題）
加熱溶融によって形成された塗膜表面にテフロン微粉末
層を均一に構成するにはテフロン微粉末を単にナイロン
樹脂粉末と混合した混合粉末では不可能であってテフロ
ン粉末が予めナイロン樹脂粒子中に均一に分散されてい
ることが必要である。(Problem to be solved) It is impossible to uniformly form a Teflon fine powder layer on the surface of a coating film formed by heating and melting, because it is impossible to simply mix Teflon fine powder with nylon resin powder. It is necessary that it is uniformly dispersed in the particles.
このことは接着層となるエポキシ樹脂及びその硬化剤に
ついても同様である。This also applies to the epoxy resin and its curing agent that serve as the adhesive layer.
組成物を構成するこれらの材料がナイロン樹脂粒子中に
均等密度で含有された粉末を得るには溶解法に依らざる
を得ないが溶解中に硬化反応が起こらないようにするこ
とが必要になる。In order to obtain a powder in which these materials constituting the composition are contained in nylon resin particles at a uniform density, a dissolution method must be used, but it is necessary to prevent a curing reaction from occurring during dissolution. .
本発明者は使用する硬化剤の反応温度以下でナイロン樹
脂を溶解可能な溶媒としてモルホリンを使用し、溶解温
度を１４０’ Ｃ以下として溶解させると共にテフロン
樹脂がモルホリンに溶解しないことを利用してナイロン
樹脂と同量のテフロン粉末（５μ〜２０μ市販品）を混
入することによって粒径１ｏ〜８０μの均一密度の粒子
を得ることに成功した。The present inventor uses morpholine as a solvent that can dissolve nylon resin at a temperature below the reaction temperature of the curing agent used, and dissolves the nylon resin at a dissolution temperature of 140'C or below, and utilizes the fact that Teflon resin does not dissolve in morpholine to form nylon resin. By mixing the same amount of Teflon powder (5μ to 20μ commercial product) as the resin, we succeeded in obtaining particles with a uniform density and a particle size of 1o to 80μ.
テフロン粉末は、ＦＥＰ、ＰＴＦＥ等溶融温度によって
求める表面層の性状に応じて選択する。The Teflon powder is selected depending on the properties of the surface layer determined by the melting temperature, such as FEP or PTFE.

2 5 kg of nylon resin, 500 g of epoxy resin, 5 g of curing agent (manufactured by Yuka Shell Epoxy, reaction temperature 150″C, 16 hours) and FEP as Teflon powder with an average particle size of 10 μ
(Melting temperature 200'C) 3kg was charged, sealed with nitrogen gas and set at 140°C 55kg/cm2 stirring speed 300 rpm.
The mixture was heated for about 1 hour and 30 minutes to dissolve it.

析出粒子を濾別し、生成粒子を真空乾燥した。When the liquid temperature dropped to about 50° C., precipitated particles were filtered out using a filter press, and the resulting particles were vacuum-dried.
平均粒径は４０μであった。The average particle size was 40μ.

された。This powder was electrostatically coated on a polished iron plate and heated in a heating furnace for 200 minutes.
℃, the epoxy resin film (2) adheres to the iron plate (1) as a second layer as shown in Fig. A molten layer of Teflon was formed on the surface of the layer as No. 37W.
（実施例２）
テフロン粉末として溶融温度２６０℃のＰＴＦＥを３．
２ｋｇとした以外は実施例１と同様にして製造した。(Example 2) PTFE with a melting temperature of 260°C was used as Teflon powder.
It was manufactured in the same manner as in Example 1 except that the weight was 2 kg.

面であってもテフロン特有の非粘着性を示す。The surface layer formed by heating was a slippery, minutely uneven surface of Teflon particles. (Figure 2) Although this coating film has lower hardness than the surface layer obtained by mixing ceramic particles, it exhibits the non-adhesion characteristic of Teflon even on rough surfaces.
